' ORE-CONCENTRATOR.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed August 2, 1912. Serial No. 712,842.

To all whom it may concern:

Be it known that I, ORRIN H. KING, a citizen of the United States, residing at Wallace, in the county of Shoshone, in the State of Idaho, have invented certain new and useful Improvements in Ore-Concentrators, of which the following is a specification.

My invention relates to ore concentrators and the object thereof is to produce a simple, efficient and reliable machine ofthis character adapted more particularly to the separation or concentration of the values or concentrates from the slime or pulp of mill tailings. I v

Speaking in general terms, my concentrator consists of a table of suitable form and inclination which is suspended and capable of a slight longitudinal movement and adapted to be jarred by suitable mechanism. The slime or pulp is arranged to be fed to the table, during which time such table is jarred with the result thatthe tailings flow over the side edges of the table into sluice ways provided therefor, the concentrates remaining upon the table. At the proper time the feed of slime is cut 0E and the sluice ways mentioned are closed by movable covers whose movement uncovers other sluice ways adapted to receive the concentrates which are now washed from the table by means of pure water admitted thereto in any suitable manner.

Other novel and advantageous features of construction and operation will be apparent from the description. hereinafter given.

In the drawings Figure 1 is an end elevation of my concentrator; Fig. 2 a plan View thereof and Figs. 3 and 4 detail views illustrating the jarring mechanism.

Referring tothe embodiment of my invention as shown in the drawings, the frame of the machine may be made in any suitable way and of any desired material and the same is here shown as made of wood and will therefore be so described. As shown, the main frame consists of uprights 1 and cross beams 2. The table frame consists of short supports 3 and also cross pieces or beams l. Suspended fromthe beams 52 is a supplementary frame comprising depending pos'ts 5 and cross strips 6.

The concentrating table is in the present instance so made as to be adjustable as to inclination and to this end it is formed of sluice ways 15 and 16.

two sections or leaves 7 hinged in suitable manner at the middle of the table along the central longitudinal axis of the machine and provided at the joint along such line with a suitable flexible flap 8. The table may be made ofany suitable material, Wood being very satisfactory, but it is obvious that other material may be employed and also that the table may be of composite formation, that is, with a metallic frame and a surface of wood or the like. As equivalents of wood I will mention linoleum, fabric, etc., which will give satisfactory concentrating action.

The highest point of the table as shown in Fig. l is along the central longitudinal axis thereof, the sections or leaves of the table inclining outwardly and downwardly toward the sluice ways hereinafter described. The table is held suspended and permitted of a slight longitudinal movement for the proper jarring action by means of the vertic'al suspending rods 9 connected at one end to bolts 9 passing through and secured to the table leaves at their outer edges and connected at the other end to bolts 9 secured to the cross beams 2 of the main frame. The angle or inclination of the table leaves may be'adjusted and held adjusted in suitable manner as by means of the horizontal rods '10 which pass through the horizontal plates or stringers 11 secured to the under surface of the leaves toward their outer or lower edges. These rods 10 are screw threaded at their ends and the adjustment is obtained by means of the nuts 12 thereon bearing against opposite sides ofthe stringers. By adjustment in the proper direction the inclination of the table leaves may be adjusted, it being understood that the nuts'13 on the ends of the suspending rods 19 are screwed up or down accordingly.

Along the opposite side edges of the table inclined sluice boxes 14 are arranged the same being mounted upon the table frame hereinbefore described. These sluice boxes have a central partition 14 thereby dividing the boxes into two separate and independent Cooperating with these sluice boxes are substantially horizontally movable covers 17 which extend the full length of the table and are adapted to cover and close either one or the other of the sluice ways according to their position. Ac cording to Fig. 1 these covers are now closing the sluice ways 15 leaving the sluice ways 16 open. By moving these covers outwardly the sluice ways 15 will be uncovered and the other sluice ways closed. One pair of these sluice ways, that is the innermost ones, are intended to carry off the tailings and the same are therefore connected at one end of the machine with suitable drainage (not shown) while the other sluice ways, which are intended for the concentrates, communicate with a suitable place ofdeposit (not shown) therefor.

Above the middle line of the table is arranged a long hopper 18 adapted to receive the slime or pulp through the pipe or conduit 19 and to feed the same through suitable bottom openings 18 to the middle of the table. This hopper is suspended from the supplemental frame in suitable manner as by means of the suspending rods 20 attached at their upper ends to the vertical posts 5. By preference the hopper is capable of a slight endwise movement imparted to it'by the jarring mechanism as hereinafter described.

At opposite ends of the machine two vertical posts 21 are provided the same being suitably braced by means of the brace rods 22 attached at their upper ends to the posts 21 and at their lower ends to the posts or beams 23. At the top of each post 21 is a metallic block 24 through which is screw threaded an adjustable rod 25 acting as a stop or abutment, the inner end thereof being arranged to be contacted by the end plate 26, there being one of these plates at each end of the table. These rods 25 are so adjusted as to permit of aslight endwise movement or swinging of the entire concentrating table and the degree of swinging is adjustable by turning these rods, or one of them, in one direction or the other. At one end of the table, the right-hand end in Fig. 2, the plate 26 has a bracket 27 having an outwardly directed roller 28 which is adapted to be contacted by means of the mutilated Wheel 29, having a series of wings and depressions, the wings being adapted to contact the wheel 28 and thereby impart a jarring motion to the table. This wheel is mounted upon the horizontal shaft 30 and the same is driven in any suitable manner as by means of power applied to the pulley 31, such shaft being journaled at its ends in the bearings 32. The action of the wheel 29 is to strike the roller 28 and to jar the table and swing it toward the left (Fig. 2) and in order to return the table to a position for another such jarring movement, a rather heavy spring 33 is provided, the same being connected at one end to the hook 34 on the bracket 27 and the other end being connected to the outer end of a lever 35 which is pivoted at 36. The purpose of this lever is to impart any desired tension to the spring 33 to which end the lever is provided along one edge with a series of ratchet teeth 35 with which cooperate a link 37 pivoted at 38. By preference the jarring motion is also communicated to the hopper to which end the bracket 27 is continued'upwardlyso that in its swinging motion it will contact with one end of the hopper.

Describing the operation of my machine, the slime or pulp is conducted through the supply pipe 19 to the hopper and the same drops through the openings in the bottom thereof upon the concentrating table which is jarred and swung slightly in the manner already described. In this operation of the table the concentrates collect upon the surface of the table while the tailings flow downwardly and over the sides of the table into the sluice ways 15, it being understood that at this time the covers 17 are in their outermost position. In the operation vof the jarring mechanism the table is jarred by contact of the mutilated wheel with the roller 28, again by the contact of the plate 26 at the other'end of the table with its adjusting screw 25 and again by the contact of the plate 26 at the other end of the table with its adjusting screw or abutment. When the proper amount of concentrates has been collected upon the table the supply of slime is cut off, the covers 17 are moved to their innermost position as shown in Fig. 1 and the concentrates are thereupon washed off the surface of the table by the force of pure water, such concentrates passing over the inclined covers 17 and being received in the shame ways 16 at the end of which they are collected in any desired way. The above described operation is thereupon repeated.
